Gecko Tequila Blue, also made from 100% blue agave, offers a little more. At 86.8 proof, it adds strength to a cocktail. "This tequila is a little less sweet and more robust than the silver. Cocktails taste more complex and shots will stand up more strongly to any condiment without losing the essence of the tequila." Gecko Tequila is a line of limited edition, super-premium blue and black tequilas. They are availably exclusively online.
